Tungsten carbide was first used in stretching mold area and has gone though cast iron mold, alloy steel mold, diamond dies, cemented carbide dies, polycrystalline module die and other developmental stages. Cemented carbide die possesses the qualities of high wear resistance, good polishing performance and low friction coefficient, it has now been widely used for drawing steel wires, nonferrous metals wires and alloy wires and rods.

1. Good Wear Resistance

Tungsten carbide possesses high wear resistance, which could guarantee long-term work of drawing die within any drawn amount and ensure the size and precision of products.

2. Excellent Polishing

Carbide has a good polishing, which can be processed like mirror, thus ensuring high-quality of metal surface.

3. Good Corrosion Resistance

The property is in the wet lubricated stretch, especially in the acidic lubricated stretch, to become more superior.
